Jimi,
You add a new property to form like this (new property name):
aMyArray[1]
Initial size is not important if you do't know beforehand. Then use it :

dimension thisform.aMyArray[ix,jx]
or :
select ... into array thisform.aMyArray
or :
aAnotherLocalArray[ix,jx] = '...'
acopy(aAnotherLocalArray, thisform.aMyArray)
etc.
However 'unlimited' rows is not an option because an array could hold 65000 elements at max (not possible with a cursor either).
You might be doing it right. Depends on what you want to do.What you're trying to do might not need arrays. ie :

with thisform.myListBox
  .Addlistitem('Item35 Column1', 35, 1)
  .Addlistitem('Item35 Column2', 35, 2)
  .Addlistitem('Item35 Column3', 35, 3)
endwith

would add Item35 in a 3 column listbox. 35 there is the unique list itemid and not need to be same as indexid (could be any other value - ie: pk of a table row). To remove an item from listbox you would use :
thisform.myListBox.RemoveItem(IndexId)

You can manage array approach more easily.
Saying it's the right way is hard :) In VFP a task could be accomplished in many ways. ie: if those addings and removing from listbox would then go to a table you might directly use a fields, alias or sql rowsource as well.
And in the future you might decide completing a particular task fits into a grid than a listbox as well :)
